The Fiatagri 45-66 is one of the tractors of the Fiat 66 Series, which Fiat launched in 1982 as its “daily” range: machines intended to handle any everyday job on small and medium farms. The 45-66 itself belongs to the second series of 1985, when the line-up was reorganised and expanded.

History of the Fiatagri 45-66
A series built for daily work

Fiat presented the 66 Series in 1982 as a new range of tractors from 45 to 80 hp (34 to 60 kW). The company called them the “daily” tractors, because they were designed to perform any everyday task on small and medium farms — the kind of work that made up most of the hours put on a farm tractor in Europe at the time. The first series was made up of the 466, 566, 666 and 766 models.
The second series of 1985
In 1985 the range was renewed. The second series of the 66 line was much wider, running from the 35-66 up through the 50-66, 55-66, 56-66, 60-66, 65-66, 70-66 and 80-66 to the 95-66. The 45-66 sat near the bottom of that list, among the smaller tractors of the family, and shared the series’ role as an all-round farm machine rather than a specialist row-crop or high-power unit.
A tractor sold under several names
The 66 Series was not sold only as a Fiat. In the United States it appeared under the Hesston brand, the American forage-equipment maker that Fiat took over in 1977, and later the same tractors were marketed with the Ford and then the New Holland names until 2003. That long life under different badges reflects how widely the series was distributed rather than any change to the basic machine.
Design and features
- Everyday usefulness: the whole series was pitched at the routine work of small and medium farms, which is where its “daily” name came from.
- Wide line-up: the second series covered models from the 35-66 to the 95-66, so a buyer could stay within one family of tractors as the farm grew.
- Several badges: the same range was sold as Hesston in the United States and later as Ford and New Holland in Europe.
- FiatAgri livery: tractors of this period wore the burgundy paint that replaced the old orange when FIAT Trattori became FIATAgri.
